HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 719,469, dated February3, 1903.

Application filed December l2 1901. Serial No. 85,602. (No model.)

To all) whom, it may concern:

Be it known that I,WILLIAM R. J EAVONS, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Hydrocarbon-Burners; andI do declare that the following is a full, clear, and exact descriptionof the invention, which will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to hydrocarbon-burners; and the invention consistsin the construction, combination, and arrangement of parts, allsubstantially as shown and described, and particularly pointed out inthe claims. I

In the accompanying drawings, Figure l is a perspective view of a newconstruction of drum forming an element embodied in this invention andconstituting also a new article of manufacture and sale. tionalelevation of the entire structure involved in this inventionandshowing'what presumablyisafixed burner-bowlandburnertubes and drum intilted relation thereto, as occurs when the burner is being started orinitially lighted by means of a match or taper. Fig. '3 is a perspectiveView of the burnerbowl alone, and Fig. 4 is a perspective view .of oneof the spacing vanes or plates on the interior of the drum.

It is of course known to be old in the present development of this artto tilt burnertubes and drum for the purpose of lighting, and this initself is not broadly new here as a function or adaptation of the parts;but there is novelty in the construction of the parts whereby this maybe done more reliably than heretofore and with certainty of having theparts always seat themselves aright,which has not been the case informer constructions, and then there is novelty also in the constructionof the drum and its connection with the burner-tubes, in that the drumis a separate and removable part and can be bodily lifted away from theburner at any time, and yet it is so associated therewith in use thatboth can be tilted together and restored to place the same as if theywere mechanically and inseparably connected, as in the old constructionsnow generally in use. This also has the further advantages of leav- Fig.2 is a sec-- ing the drum free as an article of manufacture and sale,and especially of enabling the user to remove it at any time forcleaning the parts. In the nature of things these closelyassociatedparts are liable to become more or less foul in time," renderingcleansing necessary; but when they are bolted or otherwise permanentlylocked together, as heretofore, it has been very difficult to enter theinner spaces or to reach the inner surfaces for this purpose; but bymaking the drum so that it can be lifted off from the tubes theoperation is simple and easy enough for cleansing both tubes and drum.

Now referring again to the drawings, Fig. 2, A represents theburner-bowl, havingits usual tubular and oil-supplying arms Zandprovided according to this invention with a substantially dome-shapedinner upward extension 3. This extension rises above the outer edge 4 ofthe bowl and inclines inward all around, preferably on a somewhat-curvedline, and projecting, as it does, to a point above the lowest rows ofperforations in the inner tube 0, it serves to shield or protect saidperforations from vagrant air-drafts, and inasmuch as the burner is moresensitive to drafts at the lower air-openings than at points higher upthe protection afforded by the said extension or shield 3 contributesvery materially to the steadiness of the flame. Itis also preferablethat the shield be formed integral with the inner portion of the bowl,as the radiant heat intercepted by the said shield from the interior ofthe tube 0 is then more readily conducted to the body of the bowl, wherevaporization occurs. The top of the bowl has the usual seats 6 and 7about its top for the burner tubes B and G, which are rigidly united,and the extension 3 rises from about inner seat 7 at such elevation thatit becomes at once an unerring guide in seating the tubes both when theyare tilted for lighting and when they are replaced after removal forcleansing or other reason. Heretofore there has been constant dangerthat the burnertubes would not be brought back aright to their seats,because there was no guide which was suflicient for this purpose and forthe further reason that it was not easy to see whether they wereproperly seated. Then it also occurs that in their haste or carelessnesspersons would not see that these tubes were rightly placed before usingthem and had work inevitably followed; but by means of mypeculiarly-shaped extension 3 proper seating occurs inevitably when thetubes are lowered, because they find their places by gravity about thebase of the extension after being released by hand if they have not beenproperly seated in the first place. This of course occurs also aftertilting the burner, as in Fig. 2, for lighting through the medium of theusual asbestos ring or other lighting device. (Not shown.)

As seen in Fig. 2, the drum D hangs upon the burner-tubes and is movablewith them in that position as formerly, when they were inseparable, andto this end the drum is provided with vanes or plates 19, affixedthereto and serving to space it apart from the tubes and keep it in theright relation thereto, and these vanes have hooks c at their topengaged over the outer burner-tube, substantially as as shown. In thisway the drum is suspended upon or from the top of the burner-tubes andis easily removable therefrom, but otherwise is held in the sameoperating relation as formerly, with all the advantages found in the oldconstruction. Obviously other suitable means than the vanes here shownmay be adopted to take their place, the object in any case being toutilize said vanes as guides and spacers for the drum in respect to theburnertubes and as hooks to hang them thereon. Of course separate hooksand spacers could be used and a widely-different construction from thevanes and hooks b 0 adopted and serve the same purpose; but these arecheap and easily applied, and hence embody the present preferred form.

What I claim is 1. In hydrocarbon-burners, a set of burnertubes and adrum separated therefrom provided with spacers on its inside to hold ituniformly apart from said tubes and hooks on the said spacers to suspendthe drum from said tubes, substantially as described.

2. The combination of the burner-bowl havin g an integral annularburner-tube guide extending above the plane of the outer edge of thebowl and provided with an inwardly-converging guiding-surface above theouter edge of the bowl, a set of burner-tubes seated on said bowl aroundsaid guide, and an independent drum suspended by hooks from the top ofsaid tubes and provided with spacers to hold the drum uniformly apartfrom said tubes all around, substantially as described.

3. A drum for hydrocarbon-burners provided with vertical spacers on itsinside and books at its top to support it in a suspended position, incombination with burner-tubes engaged by said hooks, substantially asdescribed.

4. The drum substantially as shown and vertically-arranged spacers fixedat intervals to the inside of the drum and provided with inwardprojections at their top, in combination with a set of burner-tubessupporting said drum, substantially as described.

5. In hydrocarbon-burners, a set of burnertubes and a drum provided withverticallydisposed spacers on its inside to keep it equally apart allaround from the burnertubes, said spacers having inwardly-projectinghooks at their top for supporting the drum, substantially as described.

6. The inner and outer perforated tubes, and the burner-bowl providedwith an imperforate extension projecting inward and upward to a planeabove the outer portion of the bowl and above the lower perforations inthe said inner tube and forming a draft-shield for the inner tube,substantially as described.

7. The burner-bowl provided with a draftshield having an annular taperedsurface extending inward and upward to a higher plane than the outerportion of the bowl and integral with the bowl, in combination withburner-tubes having air-inlet openings behind said draft-shield,substantially as described.

8. In hydrocarbon-burners, a burner-bowl provided at its inner portionwith an inwardlyinclined annular draft-shield and tube-guide risingabove the plane of the outer portion of the bowl, in combination withburner-tubes, the inner of said tubes having perforations on a planebelow the upper edge of said shield and guide.
